摘要
介绍了当电机控制电流采样有较大干扰时的硬件滤波方法以及通过每个控制周期多次采样、识别并摒弃最大偏差点等方法来进行滤波的软件算法,提供了具体实现方法、数学模型和实验对比结果,证明了该方法的简单有效性。
This paper introduces the mechanism and use of two filtering methods, one of which is depend on an integrated module hardware suitable for sampling current that has been interfered, another one is based on the algorithm obtained by periodic multiple sampling, identifying and discarding the data of the biggest deviation. Specific implementation process, Matlab models and comparison results are provided indicating the methods are both simple and efficient.
